WELL-DERRICK.

SPECIFICATION forming part of Letters Patent N0. 751,078, dated February 2, I1904:.'

Application filed October 3l, 1903. Serial 190.179,35). (No model.)

To all whom, it may concer-u:

Be it known that I, JACOB C. KNUPP, a citizen of the United States, residing at l/Varren, in

- the well-derrick for which Letters Patent of the United States No. 7 31,109 were granted to myself on the 16th day of June, 1908; and it has among its objects to make a more substantial and durable structure, to provide sup porting means for the bull-wheel ofthe driving machinery, to provide supporting means` for the derrick-roofing, and to generally improve the construction.

Vith these and other ends in view my invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is perspective View of my improved derrick. Fig. 2 is a horizontal sectional view of the same, taken a short distance above the horizontal braces 7. Fig. 3 is a top planview. Fig. 4 is an elevation, partly in section, of the upper part of crown of the derrick. Fig. 5 is a perspective view illustrating details of construction'. Fig. 6 is a side elevation showing the roof-supportingbraces.

Corresponding parts in the several figures are indicated by similar numerals of reference.

As in my former invention, my improved well-derrick includes a base-frame composed of side sills 1 1, supporting cross-pieces 2 2 and 3. Rising from the ends of thc central transverse cross-piece 3 are two uprights 4, which are connected with the side sills 1 1 by means of inclined braces 5 5, the upper ends of which are connected together and with the braces 4 by means of U-shaped clamp bolts or clips 6, eXtendingacross the main uprights 4. Horizontally disposed braces 7 connect the inclined pieces 5 5 of each side of the frame, said horizontal braces being also connected with the inclined uprights. An additional horizontal brace 8 connects the inclined braces at the rear side of the derrick-fraine. Crossbraces 9, 10, and 11 connect the inclined uprights 4 4, said braces being secured to the rear edges of said uprights. Diagonal braces' 12 are disposed to connect the ends of the upper cross-braces 10 and 11, and diagonal braces 13 connect the under edges of the crossbrace 10 with' the rear edges of the uprights 4, said braces 13 crossing each othera short distance above `the cross-piece 9 and having their lower endssecured -to the uprights 4 below said'cross-brace 9, with which they are connected Aby bolts or in any other suitable manner.

rl `he uprights '4 are connected near their upper ends by means of transversely-disposed tie-bars 14, supporting the crown-blocks 15,

having bearings for the shaft of the pulley 16.

The ends of the crown-blocks are spaced by spacing-blocks 17, which serveto positively prevent the said crown-blocks fromcollapsing upon and interfering with the operation of the pulley. They also serve as rope-guides, as will be readily understood. The front and rear ends of the said crown-blocks are connected by suitable brace-rods y18 with the front and rear sides of the uprights.

To provide for the support of the flooring of the derrick, I provide auxiliary cross-braces 2a upon the sills 1, said cross-braces being disposed between the outer braces 2 and the central brace 3. Uprights 20, supportedv upon the rear cross-brace 2, afford bearings for the bull-wheel 21, and inclined braces 19 and 19au connect the said uprights, respectively, with the proximate cross-brace 2EL and with the central cross-brace 3.

Stay-rods 22 and 23, four of each, connect the upper end of the derrick and an intermediate portion of the same with the ends of the sills, each of said stay-rods being provided near its lower end with a turnbuckle 24, by means of which they may be tightened. In my former patent four such stay-rods are shown connect- IOO ing the upper extremity of the derrick with the ends of the sills; but the four additional stay-rods added by my presentA invention are found to materially brace and strengthen the device and enable me to effect a saving in lumber and other material, since lighter material may be employed when these additional stay-rods are used. I thus eect a gain in the lightness of the structure, and the construction, besides, is rendered more economical.

The 'braces 5 5 are provided with suitablydisposed inwardly extending brackets 25, which are supported by metallic hangers or rods 26, connecting the outer ends of said brackets with the braces 5. Said brackets serve to support the sides 27 of the derrickroof.

Ladders 28 are secured to one of the uprights 4 by means of bolts 29 and braces 30. By this construction the top of the derrick is made conveniently accessible whenever it shall become necessary to repair or adjust the parts connected with the top of the derrick, while, on the other hand, when the derrick is to be dismantled for the purpose of transporting the same from one place to another the ladders may be readily detached and separated from the timbers ofthe derrick.

The tie-bars, which serve as supports for the crown-blocks, as well as the said crown-blocks, are provided with slots, as 31, whereby they may be relatively adjusted, so as to bring the pulley directly over the drilling-hole, the necessity ofrwhich is readily understood. By the construction described the adjustment may be very easily and accurately effected.

From the foregoing description, taken in connection with the drawings hereto annexed, thc operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains.

The parts constituting the derrick are so distributed and the relative strength is so proportioned that no superiiuous weight is employed. The resistance is uniformly distributed throughout, so that a very economical structure is produced which will efficiently resist the strains to which it is liable to be subjected.

Having thus described my invention, I claimf l. In a derrick, a base comprising sills and cross-pieces resting upon and connecting said sills, upwardly-converging uprights rising from the central cross-braces, inclined braces connecting said uprights with the sills eXteriorly adjacent to the outer cross-braces, horizontal braces connecting said inclined braces at the sides and at the rear end of the derrick, an inclined brace connecting the rear horizontal brace with the proximate crossbrace upon the sills, and uprights framed and supported upon the rear cross-pieces and connected at their upper ends with the rear hori- Zonta] brace and forming supports for the shaft of the bull-Wheel.

2. Ina derrick, a base, upwardly-converging uprights, connecting and bracing means for said uprights, brackets extending inwardly from the latter, hangers connecting the free ends of said brackets with the said uprights, and derrick-roof sections supported mainly by the said brackets.

3. In a derrick, a base comprising sills and cross-pieces supported thereon, uprights supported upon and rising from the central crosspiece, said uprights converging in an upward direction, crossbraces connecting the said uprights, diagonal braces connecting the said uprights intermediate the uppermost crossbraces, and diagonal cross-braces connecting the uprights, said diagonal braces being eX- tended across and below the lowermost crossbrace.

4. In a derrick, a pair of main uprights supported upon abase-frame and converging upwardly, tie-bars connecting the upper ends of said uprights, crown-bars connected adjustably with said tie-bars, said crown-bars and tie-bars being each provided with slots, and

connecting-bolts adjustable in said slots, and

a pulley mounted between the crown-blocks.

5. In a derrick, a pair of main uprights supported upon the base-frame and converging upwardly, tie-bars connecting the upper ends of said uprights, crown-blocks supported upon said tie-bars, spacing-blocks interposed between the ends of the crown-blocks, and a pulley journaled between the latter.

6. In a derrick, a base-frame, a pair of upwardly-converging uprights supported thereon, side bars connecting the upper ends of said uprights, crown-blocks connected adjustably with said tie-bars and spaced apart by means of spacing-blocks, a pulley journaled between said crown-blocks, and brace-rods connecting the latter with the uprights.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

JACOB C. KNUPP. Witnesses:
